Abstract (en)
A semi-automatic TIG welding apparatus comprises: a torch handle 4 provided with a welding switch 13; a wire feeding curved nozzle 8 which is disposed within the torch handle 4 and is curved at a point slightly extended from the torch handle 4; a TIG torch supporting arm 17B which is fixed to a TIG torch 1 which has a shielding gas hose 14 and center gas hose 24, the TIG torch supporting arm 17B being formed on the inside thereof of an electroconductive material; water-cooling welding cable hoses 15 and 16 which are attached to and extend from the lower portion of a water tank 18 through the inner side of the torch handle 4 and to the inner side of the TIG torch 1, the water-cooling welding cable hoses 15 and 16 being formed with electroconductive cables being provided therein and structured such that water flows through the water-cooling welding cable hoses 15 and 16; a TIG torch rotation block 12 which is provided to the wire feeding curved nozzle 8 and fixes the TIG torch supporting arm 17B, the TIG torch rotation block 12 further being provided with a TIG torch rotation fixing screw 11 and being formed of an electroconductive material; and an electroconductive welding cable 23 which is disposed within the wire feeding curved nozzle 8 and makes contact with the inner side of the torch rotation block 12. Thus, a semi-automatic TIG welding apparatus is provided wherein a TIG welder can freely adjust the position of the welding wire, and wherein the welding wire can be inserted to an ideal position, and also wherein the wire feeding curved nozzle and thus the wire do not fluctuate, resulting in great savings in the expenses and time related to TIG welding, and also in the amount of labor on the part of the welder. <IMAGE>
